The microorganisms that have developed resistance to available therapeutic agents are threatening the globe and multidrug resistance among the bacterial pathogens is becoming a major concern of public health worldwide. Bacteria develop protective mechanisms to counteract the deleterious effects of antibiotics, which may eventually result in loss of growth-inhibitory potential of antibiotics. ESKAPE ( and spp.) pathogens display multidrug resistance and virulence through various mechanisms and it is the need of the hour to discover or design new antibiotics against ESKAPE pathogens. In this article, we have discussed the mechanisms acquired by ESKAPE pathogens to counteract the effect of antibiotics and elaborated on recently discovered secondary metabolites derived from bacteria and plant sources that are endowed with good antibacterial activity towards pathogenic bacteria in general, ESKAPE organisms in particular. Abyssomicin C, allicin, anthracimycin, berberine, biochanin A, caffeic acid, daptomycin, kibdelomycin, piperine, platensimycin, plazomicin, taxifolin, teixobactin, and thymol are the major metabolites whose antibacterial potential have been discussed in this article.
对现有治疗药物产生耐药性的微生物正在威胁全球,细菌病原体中的多重耐药性正成为全球公共卫生的一个主要问题。细菌会形成保护机制来对抗抗生素的有害影响,这最终可能导致抗生素失去生长抑制潜力。ESKAPE(及 属)病原体通过各种机制表现出多重耐药性和毒力,当下迫切需要发现或设计针对ESKAPE病原体的新型抗生素。在本文中,我们讨论了ESKAPE病原体对抗抗生素作用所获得的机制,并详细阐述了最近发现的源自细菌和植物来源的次生代谢产物,这些次生代谢产物总体上对病原菌具有良好的抗菌活性,尤其是对ESKAPE微生物。阿比斯米星C、大蒜素、炭疽霉素、小檗碱、生物chanin A、咖啡酸、达托霉素、杀稻瘟菌素、胡椒碱、普拉霉素、普拉佐米星、紫杉叶素、替考拉宁和百里酚是本文讨论了其抗菌潜力的主要代谢产物。
